Tekom, why fine me for your mistakes??

Since I opened my LTE wifi account in October 2017 my monthly Telkom debit order has never debited my bank account. According to my bank FNB, Telkom has no debit order agreement with FNB or has NEVER attempted to debit my account. I continued to raise this with Telkom without rectification. Because of this I pay monthly via credit card online or EFT. But Telkom continue to fine me with a R200 fine for an unsuccessful debit order for a debit order that they havent submitted?? I am happy to continue paying manually but stop issuing me with R200 penalties and refund all the previous penalties that I have paid to avoid having my service cut.
